SPINNING-SPINDLE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 493,034, dated March 7,1893. Application filed July 23, 1892. Serial No. 441,029- (No model.)

To all whom it may concern:

Be it known that I, HENRY D.KLoTs,acitizen of the United States,residing in the city, county, and State of New York, have invented acertain new and useful Improvement in Spinning-Spindle Supports, ofwhich the following is a specification.

My invention relates to those supports for the upright bobbin-carryingspindles of silk and other spinning machines wherein the rig idlycombined bolster and step bearing of the spindle is allowed a lateralmovement on the spindle rail, resisted by a stiff spring, to accommodatethe deviation of the spinning spindle due to an unbalanced load andthereby permit a higher rate of speed and prevent vibration and itsresulting disadvantages. This deviation of the body of the spindle andof its foot has heretofore been accommodated by a spring-heldbolster-and step-bearings, yielding both laterally and longitudinallyindependently of each other, to, supposedly, better accord with thelocal character of the deviation on the spindle; a spring-heldintegralbolster and step-bearing has also been mounted by a flat collar upon aflat shoulder in the bolster case so as to yield both laterally andlongitudinally, its collar lifting upon said shoulder; but all thesedevices where the spring-held spindle bearings have been free to yieldboth laterally and longitudinally as above have failed to do away withthe vibration. I have, however, effectually accomplished the resultsought in a simple manner by my invention, which consists briefly of aspring-held rigidly combined bolster and step spindle bearing mounted onthe rail by means of a ball-and-socket or other joint by which everypoint of the combined bearings and hence of the spindle-blade is allowedand compolled to move, when vibrating under an unbalanced load, in anydirection in an arc of a circle circumscribed about one and the samefixed center.

In order that my invention may be clearly ascertained, I shall firstdescribe in detail the manner in which it may be carried into effect andthen particularly point out the invention in the claim.

Reference is to be had to the accompanying drawings forming part of thisspecification in Which- 7 Figure 1 represents in sectional elevation aspinning spindle and its support embodying my invention. Fig. 2 is asimilar view of a modification of the same. Fig. 3 is a similar view ofanother modification of the same. Fig. 4 represents in side elevationanother form of spindle-support embodying my invention, a bobbin beingshown in place on the spindle. Fig. 5 is a sectional side elevation ofthe same. Fig. 6 is a sectional plan view of the same on the line 6-6,Fig. 5. Fig. 7 represents in sectional side elevation another form of myinvention. Figs. 8 and 9 aresectional side and plan views respectivelyof still another form of spindle support embodying my invention.

In all the figures like letters of reference designate correspondingparts.

In all the figures,A designates the spindleblade, B the sleeve-whirl, Othe cylindrical bolster-bearing of the spindle, D the stepbearing of thesame and E the bearing-supporting case. The lower end of the spindleblade A is represented as tapered to form an oil chamber within thebearing.

In the preferred form of my invention, shown in Fig.1, I form thebolster-bearing C integrally with the step-bearing. D, and the whole,just below the sleeve-whirl B, with a spherical enlargement or ball F,which is fitted to work within a spherical socket G formed in the fixedsupporting case E, so that the combined bolster and step bearing 0 D,and hence the contained spindle, can swing universally about the fixedcenter of the ball-andsooket joint thus formed. Astiff spring H isstretched between the lower end of the combined bolster and step-bearingO D and a suitable fixed support J directly beneath the same to hold thecombined bearing 0 D yielding in its normal position, 2'. 6. itsposition when at rest. When the spindle, owing to an unbalanced load,from the bobbin or otherwise, tends, in spinning, to deviate laterallyfrom its normal position, the universal mounting permits the combinedbearing 0 D, and hence the spindle, to swing laterally on its fixedcenter against the tension of the holding spring H, until a new balanceis attained, and on a re balancing of the load thespringHinstantaneously returns the bearing and spindle to the normalposition. Long-continued use of this arrangement has proven that by thuspermitting the spindle to swing universally about a fixed center againstthe springtension, all vibration is absolutely taken up and removed.

In Fig. 2, the spring-held spindle bearing 0 D is similarly mounted on aball-and-socket universal joint, but the spindle-bearin g itself is ofdifferent character, the spindle-blade A being tubular and receivingwithin it the bolster and step bearing 0 D, after a well-known design.

In Fig. 3 the construction is similar to that shown in Fig. 1, save thatthe ball F and socket G are hemi-spherical, and are located at the lowerend of the combined bearing C D, the holding spring H being compressedbetween the flat top of the ball F, and the case E.

In Figs. 4, 5, and 6, gimbals K are shown employed, instead of theball-and-socket joint of Fig. 1, to mount thespring-held combinedbearing 0, D, universally in the case A. The action however is preciselythe same as before.

The form of the invention shown in Fig. 7 is similar to that illustratedin Fig. 3, save that a universal pivot bearing L, is substituted for thehemispherical ball-and-socket.

In the modification illustrated in Figs. 8 and 9, the universal bearingis like that of Fig. 7, but, instead of the coiled compression spring Hshown therein, erect straight springs H bearing radially against a widecollar L on the bearing 0 D, are employed to hold the bearing in normalposition,

I am aware that a rigidly combined bolster and step bearing such asdescribed herein has heretofore been flexibly mounted on the rail so asto be universally movable thereon, to

the same end as my invention, but the flexible joint has beenformed ofeither a flexible packing, or abutting shoulders other than trulyspherical, or otherwise so that the motion of the bearing and spindlewas not about an absolutely fixed center, while in each and every formof my invention illustrated, such a motion is compelled.

The ball-and-socket gimbal, and cone pivot joints herein shown anddescribed are each properly termed a universal pivot joint, and I sodistinguish them in the claim from the prior universal joints abovereferred to, which, while rendering the combined bolster and stepbearing capable of movement in all directions, do not confine suchmovement to arcs of circles circumscribed about the same absolutelyfixed center, as does my universal pivot joint, by which alone can thenatural, like tendency of the combined hearing from its unbalanced loadbe properly accommodated.

I claim- A rigidly combined bolster and step bearing for a spinningspindle mounted on the universal pivot joint herein described, the saidcombined bearing being held in a normal position by a spring, but freeto move in everydirection from the said normal position against thetension of said spring and con fined in said movements to arcs ofcircles all circumscribed about the one fixed center of said universalpivot joint, as hereinbefore set forth.
